Hi
Welcome to the MedHelp forum!
Commonest cause of chronic nausea is acidity. Let her take omeprazole (empty stomach in morning) and antacid gel and see if it helps. Liver and kidney dysfunction is another cause. Hence kidney and liver function tests should be done. Other causes are diabetes and hypothyroidism. Electrolyte imbalance too can cause nausea. IBS, gluten or lactose intolerance, parasites in gut too can be the cause. A stool test should be done for worms, giardiasis etc. Also if nothing is found then food challenge test to detect food intolerance should be done. Hope this helps. Take care!
has she been checked for kidney problems? that will cause these symptoms. the dr shouldve checked this already. if he didnt, find a new dr. keep having tests and have drs look for things until they find a cause. if its been for months, its doubtful to be a virus. ulcers is questionable because you can get ulcers on any organ in the body, especially if youre genetically prone to things like lupus or any of its adjoining diseases. a lot of syndromes, deficiencies and diseases can be determined by certain antibody/ dna tests, if she hasnt had any done, it might be time for some. until they find something, your best bet is to buy her some marijuana. it may be illegal where you are, you may have to do something you wouldnt normally consider, but it is your best bet to get her to be able to eat and keep it down. that is probably the most common reason why they give it to cancer patients and people with renal failure. they cant eat, they get too sick from treatment. the marijuana eases the symptoms so they can eat and keep it down.
